In various embodiments, a flood risk score may be determined for a property point that provides a comprehensive assessment of the property point's risk of flooding. Determining the flood risk score may include determining a flood risk characteristic for the property point and assigning a flood risk score that corresponds to the flood risk characteristic. In some embodiments, flood risk characteristics may include a difference in elevation between the elevation of the property point and an elevation of a calculated point (e.g., on a known flood risk zone boundary). Flood risk characteristics may also include a flood zone determination for the property point and / or proximity of the property point to a known flood risk zone boundary or a flood source. In some embodiments, flood risk scores may be provided on flood risk score reports.

A uterine manipulator designed to perform a total laparoscopic hysterectomy in an easy, safe and effective manner, which simplifies the surgical procedure by improving the anatomical angle of access to round ligaments, salpinges, utero-ovarian ligaments, broad ligaments, uterine vessels, anterior endopelvic fascia, lateral endopelvic fascia, but very especially to the posterior endopelvic fascia due to innovative design of said manipulator that allows the anteversoflexion movement of uterus.
